The Canadian 24-Hour Movement Guidelines for Children and Youth recommend at least 60 minutes of physical activity per day, 2 hours or less of recreational screen time per day, and 9 to 11 hours of sleep per night for 5 to 13 years old and 8 to 10 hours per night for 14 to 17 years old. This study examined the association between meeting these guidelines and psychological distress among adolescents.

The present cross-sectional sample included 6,364 students aged 11 to 20 years from the 2017 Ontario Student Drug Use and Health Survey. This provincially representative school-based survey is based on a 2-stage cluster design. A confirmatory factor analysis (CFA) was first conducted to confirm the factor structure of the K6, and structural equation modeling adjusted for age, sex, ethnoracial background, subjective socioeconomic status, and body mass index

-score was used to investigate the association between meeting the 24-Hour Movement Guidelines and K6 factors among adolescents.

The CFA demonstrated thhe 24-Hour Movement Guidelines was associated with lower anxiety and depressive symptoms among adolescents, and these associations appear mainly driven by meeting the sleep duration recommendation.Phytochemical study of Uvaria comperei afforded an alkaloid, 8,9-dimethoxy-5H-phenanthridin-6-one (1), isolated and characterised (assignment of 1H and 13C NMR) for the first time from a natural source along with two flavonoids, (2S)-5-hydroxy-7,8-dimethoxyflavanone (2) and (2S)-7-hydroxy-5-methoxy-6,8-dimethylflavone (3). Clethric acid (4), oleanoic acid (5), β-sitosterol 3-O-β-D-glucopyranoside (9), β-sitosterol palmitate (6) and a mixture of stigmasterol (7) and β-sitosterol (8) were isolated from Oxyanthus unilocularis. The structures of these compounds were elucidated using modern spectroscopic techniques including1D and 2D Nuclear Magnetic Resonance (NMR) Spectroscopy (1H, 13C, 1H-1H COSY, HSQC, HMBC) and Mass Spectrometry. Some fractions and compounds from Uvaria comperei exhibited good antifungal activity against clinical isolates and standard strains of yeast species of Candida and Cryptococcus genera while extracts from Oxyanthus unilocularis displayed weak antifungal activity. The results obtained show that Uvaria comperei could be a potential source of antifungal drugs.In the United States (US), young, Black men who have sex with men (YBMSM) are disproportionately affected by HIV. Delayed and infrequent HIV testing has been associated with the increased likelihood of YBMSM to be infected, yet unaware. Despite increased efforts to provide HIV testing to YBMSM in the US, HIV testing remains underutilized by YBMSM in the South. To develop strategies to increase HIV testing, this study sought to understand the factors that affect HIV testing utilization among YBMSM. Twenty-two HIV-positive and HIV-negative YBMSM aged 22-33 in North Carolina participated in semistructured interviews. Qualitative thematic analysis revealed that deterrents and motivators to HIV testing spanned individual, social, and structural levels. Deterrents included a low perceived risk of HIV, fear of receiving an HIV-positive test result, lack of HIV testing locations, healthcare provider mistreatment and privacy concerns due to intersectional stigma. Motivators of HIV testing included health maintenance, social support, and increased access to HIV testing. The findings from this study contribute to ongoing research that aims to address inconsistent HIV testing and late HIV diagnosis among YBMSM. Interventions to address intersectional stigma in community and healthcare settings can enhance utilization of HIV prevention services .A 22-year-old man begins with up to 12 loose stools per day, with mucus but without blood. They are present for two months, even during the night. Histological study of the biopsies which were taken during ileocolonoscopy shows Treponemas genus Brachispira. Intestinal spirochetosis is the presence of spirochetes of the Brachyspiraceace family attached to the apical cell membrane of the colorectal epithelium. The majority of the cases are reported in homosexuals or HIV-positive patients. Current theories suggest that spirochetes are normal flora but they can become pathogenic due to immunosuppression. The clinical presentation varies from typically asymptomatic to non-specific symptoms. Endoscopic findings are variable and non-specific. The histological study is diagnostic, showing spirochetes embedded in the epithelial cell border, as a "false brush border".The presence of donor-specific antibodies (DSA) has been considered to affect survival of allograft and patient after liver transplantation (LT). However, their significance is not well understood. We performed a prospective study of 32 adult patients who underwent LT in 2011 to analyse the existence of DSA, associated risk factors, and medium-term impact. Immunological determinations were performed immediately before LT and at 3, 6, 12 months and 5 years after LT. Eight patients (24.2%) presented preformed DSA. However, titres were negative in all patients 5 years after LT and there were no events associated. Eight out of 24 patients (33.3%) developed de novo DSA. After 5 years, only 2 remained positive; both were class II with high MFI values at diagnosis (over 15 000). No association was found between development of DSA and risk of rejection, graft loss, or death. However, an increase in liver stiffness values was observed in patients with persistent DSA; in one, we recorded focal sinusoidal deposition of C4d and moderate liver fibrosis. In conclusion, the incidence of DSA is high after LT. In addition, the persistence of de novo DSA could be associated with silent liver fibrosis with potential impact on graft outcomes.

Our objective is to evaluate the safety of deep sedation with Propofol administered by endoscopists or trained nurses .

Retrospective study conducted in all patients undergoing colonoscopy for colorectal cancer (CRC) screening, sedated with Propofol controlled by the endoscopy team (ET) during a period of 8 months. Different variables were recorded sex, anesthetic risk (ASA), dose of Propofol, duration of the exploration and presence of desaturation, bradycardia or hypotension.

277 colonoscopies were performed (53.4% male), with 25 (8.9%) complications related to sedation. The most frequent were cardiovascular complications (21 cases, 84%), including 15 cases of hypotension, 3 cases of bradycardia, and 3 of both at the same time. Four (1.4%) desaturations were recorded. In these cases, the mean dose of propofol (251mg), as well as the time of exploration (36±8 min) and the ASA classification were higher than in those patients without complications, or with cardiovascular events (no statistically significant difference).

Deep sedation with propofol controlled by traide ET in our screening colonoscopy program is a safe procedure. .

There is scant evidence for this technique in brain-dead donors, let alone in fulminant liver failure. We present the case of a 41 year old male with type A blood group and a diagnosis of fulminant liver. In the absence of a compatible donor, the patient received an ABOi LT (group O), with good clinical evolution.Objective During endoscopic retrograde cholangiopancreatography (ERCP) patients are exposed to ionizing radiation. Radiation dose depends upon multiple factors. Our goal was to assess fluoroscopy time (FT), radiation doses and effective dose (ED) during ERCP according to the condition that is being treated. Materials and methods A descriptive study of 369 consecutive ERCPs from January 2017 to June 2019. Patient demographic and procedure data were collected. FT, cumulative dose area product (DAP), fluoroscopy DAP, DA fluoroscopia, air Kerma, and number of radiographs. ED was estimated using specific conversion factors. Results Mean age was 73.34 years. A total of 193 subjects were male. Mean FT was 4.56 ± 0.17 min. Cumulative DAP was 2056.73 ± 188.83 cGycm2, fluoroscopy DAP was 1722.90 ± 82.26 cGycm2, and air Kerma was 85.84 ± 4.93 mGy. The number of radiographs was 2.10 ± 0.07. Mean ED was 5.34 ± 0.49 mSv. FT was statistically significantly longer for choledocholithiasis (CL), proximal malignant biliary stricture (PMBS), and distal malignant biliary stricture (DMBS) versus others (OT). Cumulative DAP was higher for PMBS (p less then 0.002). FT, cumulative DAP, fluoroscopy DAP, and air Kerma values were significantly higher for complicated CL as compared to simple CL. ED was higher for CL, DMBS and PMBS, but only significantly so (p less then 0.002) for PMBS. Conclusions FT for ERCP is variable. It increases with exploration difficulty, thus being longer in case of PMBS, as well as with the amount of radiation received by the patients and ED.Common variable immunodeficiency (CVI) is a rare disease, with an estimated prevalence of 1-10 in 100,000 individuals, and more common in the third decade of life. The etiology remains uncertain, although there are genetic factors involved in onset and progression of the disease. Gastrointestinal manifestations are present in 10-60% of the patients, with inflammatory bowel disease appearing in 2-4% of the cases. A 32-year-old male patient with common variable immunodeficiency on treatment with human immunoglobulin G, had recurrent episodes of intestinal pseudo-obstruction, which were medically treated. Imaging test showed a non-obstructive ileal stenosis, and biopsies performed during ileocolonoscopy revealed nodular lymphoid hyperplasia. The patient presented with a new clinical picture compatible with intestinal obstruction. An abdominal computed tomography was obtained, evidencing a jejunal loop dilatation secondary to a caliber change probably related to intestinal intussusception. Emergency surgery was performed, observing a scar-like stenotic area, which was resected. The postoperative period was uneventful, and the histopathological examination revealed an infiltrate compatible with Crohn-like enteropathy. Persistent activation of tumor necrosis factor α (TNF- α) may contribute to the pathogenesys of CVI-associated inflammatory enteropathy in some patients. In the last years, there have been cases treated with anti-TNF-α drugs (Infliximab and Adalimumab) resulting in favorable clinical outcomes, as described by Vázquez-Morón et al. Currently, the patient remains asymptomatic one year after surgery. Therefore, and given the abscense of other intestinal segments involved, no biologic agent neither additional therapies have been required.

Diabetes has been reported as a risk factor for hepatocellular carcinoma (HCC) in population based studies but there are controversial data in patients with cirrhosis. Otherwise, metformin could have a protective role in HCC development. The aim of this study was to know the influence of diabetes on the risk of developing HCC in patients with alcohol- and hepatitis C virus (HCV)-related cirrhosis.

We analyzed 982 Caucasian patients with alcoholic or HCV cirrhosis included from 1992 to 2014 in a HCC surveillance program and prospectively followed. The influence of diabetes on the development of HCC was analyzed by Kaplan-Meyer and adjusted with Cox regression for relevant co-factors.

At a median follow-up of 49.5 (24.0-96.0) months, 156 patients (15.8%) developed HCC. There were no differences in the cumulative incidences of HCC after 20 years between diabetic and non-diabetic patients in the global series (53.5% vs. 45.4%; P=0.26), alcoholic (50.4% vs. 45.4%; P=0.21) or HCV (60% vs. 43.1%; P=0.57) cirrhosis.
